The Most Effective Way to Get Through to Parents Who Won’t Vaccinate Their Kids

As doctors and public health officials keep trying to persuade parents to get their kids vaccinated against childhood diseases, the entreaties don’t always do much. Currently, only 69.7% of two-year-olds in the U.S. have received their full vaccine series, according to the U.S. Centers for Disease Control and Prevention—including shots against measles, mumps, rubella, diphtheria, tetanus, polio, and more. Just 10.1% of kids ages six months to four years have vaccine coverage against COVID-19.

Part of the problem is the vocal anti-vaccine movement in the U.S. and a lack of access to adequate health care services. But another issue might be that the most effective pro-vaccine communicators aren’t being used. According to a new study in the journal Pediatrics—which focused on COVID-19 vaccines in particular, but has implications for all vaccination campaigns—if you want to persuade parents to get their children vaccinated, the most convincing arguments may come not from health-care professionals, but from other trusted parents.

In the study, the researchers assigned 898 white, Black, and Latinx parents in Chicago—whose children had not yet received COVID-19 vaccines—to one of four groups. Each group was assigned to read a different message about COVID-19 vaccinations, after which parents were asked whether they were “not likely,” “somewhat likely,” or “very likely” to get their child vaccinated:

  • One of the messages, dubbed the “well-tolerated” message, asked the parents to imagine that a doctor or nurse contacted them encouraging them to get their child vaccinated, adding that “kids can sometimes have side effects…like body aches and fever. But these don’t happen for all children and the effects last only a day or two.”
  • The second message, dubbed “safe and tested,” asked the parents to imagine the same scenario, but this time the doctor or nurse stressed that the COVID-19 vaccine had been tested “around the United States [and] that the vaccine is effective, and it is also as safe as other vaccines that are given to kids.”
  • The third message, called “trusted parent,” asked the parents to imagine that they heard from other parents they trust saying that they had vaccinated their own children against COVID-19. “Some of them say that they weren’t sure at first about whether the vaccine is safe for kids,” the message read, “but they ended up deciding it was the best way to fight COVID-19 and the vaccination went fine. They want to keep their kids protected.”
  • The fourth group read a control message that simply told parents that the COVID-19 vaccine was available and recommended for children.

    The differences among the groups were marked. Overall, 37.5% of people who read the control message said afterwards that it was very likely that they would get their child vaccinated. The “well-tolerated” message did a little better, at 41.5%. Parents who read that the vaccine was “safe and tested” came in at 48.9%. But for the trusted parent scenario—the only one in which the vaccine message came from a non-medical professional—the “very likely” figure was 53.3%.

    “This study tells us that parents really value what they hear from other parents who they trust when it comes to decisions about vaccinating their children,” says Marie Heffernan, lead author of the paper and assistant professor in the department of pediatrics at Northwestern University Feinberg School of Medicine. “The current study was in the context of the COVID-19 vaccine for children, but we can think about this in terms of other routine childhood vaccinations as well.”

    Not all of the findings were uniform across the sample group. Ethnicity, in particular, made a difference. In the “trusted parent scenario, for example, 61.1% of white parents said they would be very likely to vaccinate their child, compared to 51.6% of Latinx parents and 49.9% of Black parents. Each of the other scenarios saw similarly varying rates by ethnicity.

    Heffernan was not surprised by those results and believes that history is at least partly to blameคำพูดจาก สล็อตเว็บตรง. “We know that the historical context of medical research in the U.S. has led to distrust of medical research among communities of color,” she saysคำพูดจาก สล็อตเว็บตรง. “This distrust is justifiable, and it’s important that we in pediatrics, public health, and medicine continue to work to build that trust.”

    The study does not conclude that pro-vaccine messages from healthcare providers are of no value at all. The relatively high scores among the people who read the “safe and tested” message indicates that parents do pay heed to what their doctors and nurses tell them. But it may help even more if those medical authorities have children of their own and communicate that to parents. “In some cases, a healthcare provider, like a doctor or nurse, might also be a trusted parent,” says Heffernan. “Our results tell us that health care providers might be more effective at changing minds if they mention, for example, that they encouraged their own family members to get vaccinated.”
